Security in web development is essential for protecting both user data as well as the integrity of the applications. In a digital environment where cyber threats are constantly evolving, implement security practices from the early stages of the web development is crucial to avoid attacks that can compromise the privacy of the users and the reputation of the company. Measures such as the protection against code injections, secure authentication, and encryption of data will help to build web sites and web applications robust, secure, and reliable.
The security in the web development is a priority that involves techniques and tools that are designed to protect web sites and web applications against malicious attacks. The vulnerability in an application can compromise not only the user data, but also the reputation of the company. To address the security from the early stages of development is essential to ensure a safe experience and reliable for the users.
1. Protection against Common Attacks
- Cross-Site Scripting (XSS): This attack is based on the injection of malicious scripts in the user's browser. To avoid this, it is essential to cleanse, and validate user input, in addition to using methods such as Content Security Policy (CSP) to restrict the execution of unauthorized scripts.
- Cross-Site Request Forgery (CSRF): In this attack, the attacker tricks the user to perform unwanted actions on sites where it already has logged in. The solution is to use tokens CSRF to verify the legitimacy of each request sent by the user.
- SQL injection: Handling of SQL queries by injecting malicious code can allow unauthorized access to the database. To prevent this, it is recommended to use prepared statements (Prepared Statements) and ORM (Object-Relational Mapping), which protect against modifications malicious.
2. Authentication and Authorization Secure
- Multi Factor authentication (MFA): The authentication of two or more factors ensures that the access to the system is made solely by the legitimate user, which reduces the possibility of unauthorized access.
- Management of Secure Sessions: To set the duration of the sessions, and use secure cookies, and encrypted with the label HttpOnly prevents theft of sessions, thereby reducing the risk of session hijacking attacks.
- Use of OAuth and JWT: These tools and protocols that enable applications to manage access without compromising credentials. OAuth is ideal for third-party authorization, while JWT offers a secure solution to validate the authenticity of the requests.
3. Encryption and Data Protection
- SSL/TLS and HTTPS: Encryption of data in transit using HTTPS is essential to ensure that the information between the server and the browser of the user is protected from eavesdropping or interception.
- Encryption of Data-at-Rest: In addition to protection in transit, the confidential data stored in the database must be encrypted to prevent unauthorized access.
- Hashing Secure Passwords: Instead of storing passwords in plain text, uses algorithms hashing insurance, such as bcrypt or Argon2, to protect the credentials in case of an attack of a data breach.
4. Update and Ongoing Maintenance
- Patch Regular: Security vulnerabilities are constantly discovered. Maintain the software, frameworks, and libraries up to date reduces the risk of attacks exploiting known vulnerabilities.
- Security monitoring: Tools of monitoring and intrusion detection allow you to identify suspicious activity and potential threats in real time.
- Penetration testing (Pentesting): Perform security audits periodic by pentesting help to discover and fix vulnerabilities before they can be exploited by attackers.
5. Compliance, and Privacy
- GDPR and CCPA: Comply with privacy regulations, such as the General Regulation of Data Protection (GDPR) and the Privacy Act California Consumer (CCPA), it is crucial to protect the user's privacy and to avoid legal sanctions.
- Management of Consent to Cookies: Include a system of consent cookie allows users to decide if they want to share their data, in addition to complying with the privacy requirements of the current regulations.
Conclusion
The security in the web development is not an option, but a responsibility. Implement measures of protection in each phase of the development ensures that the application will be less vulnerable to attacks and protect users ' data, as well as the reputation of the company. Keep up to date on security best practices and perform regular audits allows developers to build applications robust and secure in a digital environment of constant change.
